A nurse is caring for a client who has a hemoglobin of 10.8 g/dL and a hematocrit of 30%. The nurse should expect the client is at risk for which of the following conditions?
Cellular hypoxia
Fluid retention
Prolonged bleeding
Impaired immunity
The Correct Answer is A
Choice A rationale:
Cellular hypoxia occurs when cells do not receive enough oxygen to meet their metabolic demands. Hemoglobin is the protein in red blood cells that carries oxygen from the lungs to the tissues. A hemoglobin level of 10.8 g/dL is below the normal range for adults (14-18 g/dL), indicating that the client has anemia. Anemia reduces the oxygen-carrying capacity of the blood, which can lead to cellular hypoxia.
Here is a detailed explanation of how anemia can lead to cellular hypoxia:
Decreased oxygen-carrying capacity: Anemia results in fewer red blood cells or reduced hemoglobin levels within those cells. As a consequence, the blood's ability to transport oxygen to the tissues is diminished.
Impaired oxygen delivery: Oxygen is transported to the tissues through the bloodstream, attached to hemoglobin within red blood cells. With fewer red blood cells or reduced hemoglobin, the delivery of oxygen to the tissues is compromised.
Decreased oxygen availability at the cellular level: As oxygen delivery is impaired, less oxygen is available to the cells for metabolic processes. This insufficient oxygen supply leads to cellular hypoxia.
Impaired cellular function: Cells require oxygen to produce energy through a process called aerobic respiration. Cellular hypoxia disrupts this process, leading to impaired cellular function.
Tissue and organ dysfunction: When a significant number of cells within a tissue or organ experience hypoxia, the function of that tissue or organ can be compromised. This can manifest in various symptoms and complications, depending on the affected organs.
Common signs and symptoms of cellular hypoxia:
Fatigue Weakness
Shortness of breath Pale skin
Dizziness Headache Chest pain
Tachycardia (rapid heart rate) Cognitive impairment

Correct Answer is A
Explanation
Rationale for Choice A:
Ineffective airway clearance is the most immediate and life-threatening concern in the postoperative period following a radical neck dissection. This procedure involves extensive removal of lymph nodes and tissues in the neck, which can significantly disrupt normal respiratory function and airway patency. Here's a detailed explanation of the factors contributing to this risk:
Altered Respiratory Anatomy: The surgical resection of tissues and lymph nodes can directly impact the structure and function of the airway. This includes potential narrowing of the trachea, vocal cord dysfunction, and impaired laryngeal movement, all of which can hinder effective airflow.
Thick, Copious Secretions: The surgical trauma and manipulation of tissues often lead to increased production of thick, tenacious secretions in the respiratory tract. These secretions can obstruct the airway, making it difficult for the patient to clear them effectively.
Impaired Cough Reflex: The surgical dissection may disrupt the nerves involved in the cough reflex, which is a crucial mechanism for clearing secretions from the airway. This further impedes the patient's ability to maintain a patent airway.
Risk of Aspiration: Accumulation of secretions in the airway elevates the risk of aspiration, which can lead to pneumonia and other serious complications.
Potential for Edema: Postoperative swelling in the neck tissues can further compress the airway, exacerbating the risk of obstruction.
Nursing Interventions for Ineffective Airway Clearance:
Prompt recognition and management of ineffective airway clearance are essential to prevent respiratory compromise and ensure patient safety. Here are key nursing interventions that should be prioritized:
Frequent Assessment: Continuously monitor respiratory rate, effort, breath sounds, oxygen saturation, and level of consciousness for any signs of respiratory distress.
Positioning: Elevate the head of the bed to 30-45 degrees to promote lung expansion and facilitate drainage of secretions. Suctioning: Regularly suction the airway to remove secretions, using aseptic technique and proper suctioning pressure.
Deep Breathing and Coughing Exercises: Encourage and assist the patient with deep breathing and coughing exercises to mobilize secretions.
Humidification: Provide humidified oxygen or use a nebulizer to help thin secretions and make them easier to expectorate.
Chest Physiotherapy: Perform chest physiotherapy techniques, such as percussion and vibration, to loosen secretions and promote their removal.
Monitoring Fluid Balance: Maintain adequate hydration to help thin secretions, while closely monitoring fluid intake and output to prevent fluid overload.
Addressing Other Choices:
While the other choices may also be relevant concerns in the postoperative period, they do not pose the same immediate threat to life as ineffective airway clearance.
Correct Answer is B
Explanation
Choice B rationale:
Checking the patency of the tubing is the first and most crucial step in addressing the lack of urinary output in this patient. Here's a detailed explanation of why this is the priority action:
Addresses the Most Likely Cause: Obstruction of the urinary catheter tubing is the most common and easily reversible cause of sudden cessation of urinary output in a patient with a continuous bladder irrigation system.
Prevents Complications: A blocked catheter can lead to a number of serious complications, including: Bladder distention, which can cause pain, discomfort, and potential bladder damage.
Urinary retention, which can increase the risk of urinary tract infections (UTIs) and kidney damage. Hematuria, or blood in the urine, due to clot formation in the bladder or catheter.
Non-Invasive Intervention: Checking the tubing is a simple, non-invasive procedure that can quickly identify and resolve the issue without requiring further interventions or delays in care.
Prioritizes Patient Safety: It's essential to promptly address any potential urinary obstruction to prevent the aforementioned complications and ensure patient safety.
Rationale for Other Choices:
Choice A: Administering a prescribed analgesic:
While pain management is important, it does not directly address the lack of urinary output. Pain medication would be appropriate if pain were assessed to be the cause of the decreased output, but it's not the first priority in this situation.
Choice C: Notifying the provider:
Although the provider should be informed of the situation, checking the tubing for patency is a necessary first step to gather more information and potentially resolve the issue quickly without requiring further intervention.
Choice D: Offering oral fluids:
Increasing fluid intake might be helpful in some cases of decreased urinary output, but it's not the priority action in a patient with a continuous bladder irrigation system and a potential catheter obstruction.
